The switch operates as follows. For example, to connect input 1 to output 1, it is necessary to press the corresponding buttons of the button switch 39 on the control unit, as a result of which the driver 40 is connected via the closed contacts of the button switch to the group of disconnect outputs 7, the first 5 and second 6 outputs of the enable groups. The shaper generates a corresponding series of pulses of a certain duration arriving at the first you. water of the first and second inclusion groups. 8 the first moment, the switched on relays 4 located in these rows are turned off, and then the ones located at the intersection

of these series, the polarized relay 4, its first and second contacts are closed. After the first contact is closed, the voltage from the power source 42 is supplied to the corresponding high-frequency relay 9 and through an additional signal diode 35 and the first signal group of conclusions 34 on the display panel of the switching status 41 of the control unit. The relay 9 is turned on and connects the terminals of the contact part 13 to the terminal of the contact part 12 and connects the inputs. T with output 1. A closed second contact 38 of the polarized relay according to the second 36 and third 37 signal groups of outputs signals the circuit

5 controls the passage of information 43 of the control unit about the generated high-frequency channel input 1-output 1, during information passing through a high-frequency channel input 1-output 1 control circuit 43

0 blocks the operation of polarized relays 4 in the first horizontal and first vertical rows.

When the button is pressed, the grounding of the button switch 39 on the control unit 5, as a result of which the driver is connected via the closed contacts of the button switch through the third auxiliary terminal 19 to the additional polarized relay 17.

0 Shaper 40 generates a pulse of a certain duration arriving at the switching winding of the additional polarized relay 17, while contact 23 closes and contact 24 switches.

5 After the contact 24 is closed, the voltage from the power source 42 is supplied to an additional high-frequency relay 15, and the output of the contact part 24 being connected to the contact part 26 signals through the sixth additional output 22 on the display of the switching status 41 of the control unit for relay activation 17 and, respectively, relay 15. Relay 15 is turned on and connects the output of the contact part 28 to pin 5 of the part 29 and connects all the outputs of the switch to the device body (grounding of the outputs in the absence of commutation).

When the button is pressed, the isolated button switch 39 on the control unit is isolated, the driver 40 is connected via the closed contacts of the button switch and through the fourth additional output 20 to the additional polarized relay 17, the driver

5 generates a pulse of a certain duration arriving at the turn-off winding of the additional polarized relay 17, with this contact 23 opens, and the output of contact part 24 closes with the output of contact part 25. After opening

of contact 23, the voltage from the power source 42 ceases to flow to the first additional high-frequency relay 15, and the closed contact parts 24 and 25 signal through the fifth additional output 21 on the display panel of the switching status of the control unit to turn off the additional polarized relay 17 and, accordingly, the relay 15. The relay 15 is turned off and all contact outputs of the switch are disconnected from the device case by switching contact parts 28 and 29 (isolation of outputs in the absence of commutation).

In an emergency situation, in the absence of a supply voltage, the second additional high-frequency relay 16 is turned off and connects its input parts 32 and 33 to input, M and output K. Thus, in the de-energized switch, there always exists a formed high-frequency channel input in.M-out.K.

The present invention, in comparison with the prototype, allows switching of high-frequency signals h, and due to the introduction of high-frequency relays; ground or isolate the outputs of the switch by introducing a first additional high frequency relay; when removing the supply voltage, receive or transmit a high-frequency signal through the generated high-frequency channel by introducing a second additional high-frequency relay.,
